Samuel Michael Fuller (August 12, 1912 – October 30, 1997) was an American screenwriter, novelist and film director known for low-budget genre movies with controversial themes.

He was born Samuel Michael Fuller in Worcester, Massachusetts, the son of Benjamin Rabinovitch, a Jewish immigrant  from Russia, and Rebecca Baum, a Jewish immigrant from Poland. After immigrating to America, the family's surname was changed from Rabinovitch to "Fuller" possibly by inspiration of a Doctor who arrived in America on the Mayflower.  At the age of 12, he began working in journalism  as a newspaper  copyboy. He became a crime reporter  in New York City at age 17, working for the New York Evening Graphic. He broke the story of Jeanne Eagels' death.  He wrote pulp novels and screenplays  from the mid-1930s onwards. Fuller also became a screenplay  ghostwriter  but would never tell interviewers which screenplays that he ghost-wrote explaining "that's what a ghost writer is for".
